Now Vanzetti Engineering is significantly increasing its deliveries of high-pressure pumps for marine use. This demand is due to the great demand in the sector that integrates the product type in the supply systems of marine engines. Since 2021, the number of orders for VT-3 type cryogenic high-pressure piston pumps has increased significantly. This is due to the new market trend of using high-pressure systems. This particularly affects giant ships that run on natural gas, such as container ships, bulk carriers, gas and chemical tankers, and car carriers. Giancarlo Geninatti Crich, Vanzetti Engineering’s LNG Marine Sales Manager, confirms, “New ships are increasingly using methane engines for their propulsion systems. There is a high demand especially for high pressure systems. In this regard, the trend has changed – just a few years ago, low-pressure engines were preferred.”
More efficient and sustainable engines
This trend, which has emerged in recent years, has its origins in the technological development of engines in terms of sustainability and efficiency. ME-GI high-pressure two-stroke engines from the MAN company are used to power today’s giants of the seas. They use VT-3 low-temperature piston pumps in a double, triple or quadruple configuration.
“Already in 2019, the company delivered the first products for high-pressure applications in the marine sector. By 2020, 90% of the cryogenic pumps sold in this sector had low-pressure technology (up to a maximum of 20 bar). Since the beginning of 2021, however, orders for high-pressure pumps (up to a maximum of 350 bar) have increased considerably. Our current order intake includes a 50% share of high-pressure and 50% of low-pressure pumps.”

From 2021 to date, the company has delivered a large number of VT-3 machine groups in double and triple configuration for more than 30 vessels equipped with high-pressure supply systems and in demand worldwide, mainly from customers in China, Korea, Singapore and Norway.
Safety, reliability and low maintenance
Vanzetti Engineering’s VT-3 cryogenic piston pumps are an evolution of the previous VT-55 model. Depending on the desired flow rate, the pumps are available in single, double, triple or quadruple configurations. Their maximum pressure is 420 bar. The VT-3 model represents an ideal solution in terms of performance, safety, reliability and maintenance optimization. Its delivery can be made on a transport and installation frame that supports both the pump and all the accessories (sensors, instruments and valves) necessary for safe and reliable pump operation.Innovative high pressure pumps for the marine sector
Stabilization of plastic exhaust systems during implementation
According to the exhaust specialist ATEC from Neu Wulmstorf, the Vario roof flange can be mounted on all roofs with high fitting accuracy. The selection is based on the roof pitch and the required nominal size. In addition, the flange is suitable for temperature classes T200 and T250 – and ATEC has had this certified with a general design approval.
The new product combines two components: first, the flange itself, which provides a stable connection between the roof elevation and the roof structure, and second, the optional seal, a self-adhesive vapor retarder. The company provides two versions: for roof pitches between 0° and 30°, and from 30° to 60°, each in eight nominal sizes between DN60/100 and DN250/315. It is also compatible with plastic and metal exhaust systems up to a nominal operating temperature of ≤ 250 °C.
The flange consists of a stainless steel clamp to which two retaining lugs/articulated brackets are welded at the factory. This is accompanied by a cover plate measuring 450 x 450 mm and 0.5 mm thick. With the help of malleable perforated strips, the exhaust pipe together with the Vario roof flange is screwed into place. This allows the Vario to be used flexibly both in new buildings and in existing properties.

Innovative insights into emergence and classification into subtypes
One of the deadliest tumor types is pancreatic cancer . The disease is often only discovered in locally advanced or metastasized tumor stages, when surgical intervention comes too late. Researchers led by Dr. Ivonne Regel of LMU Klinikum in Munich have now gained important new insights into the causes of tumor development. They have also succeeded in defining different tumor subtypes based on differences in their metabolic programs. Funded by the Wilhelm Sander Foundation, they are thus making a significant contribution to early detection and to individualized medicine in order to improve the chances of recovery for pancreatic cancer patients.
Pancreatic ductal adenocarcinoma, also known as pancreatic cancer, is a relatively rare but particularly malignant disease. It represents the fourth leading cause of cancer-related deaths in the European Union, and only about 10 percent of patients survive the first five years after diagnosis. This is due to aggressive growth and late diagnosis of the tumor. Pancreatic cancer often manifests itself only after other organs have already been affected and metastases are present. To improve the chance of cure for pancreatic cancer patients, it is of great urgency to find new biomarkers for early detection. Another essential step is to identify tumor-specific signaling pathways that cause aggressive disease progression in order to identify new targets for therapeutic approaches.
TLR3/IRF3/IRF7 signaling pathway critical for pancreatic cancer development
Pancreatic cancer development is a dynamic process involving tissue damage and inflammatory response in the pancreas. When pancreatitis occurs, the organ has a self-healing mechanism. Normal pancreatic cells can divide to replace damaged tissue. Molecules released during inflammatory and tissue-damaging processes are recognized by cell receptors, relaying signals that promote cell survival and division.
However, in pancreatic cells, this can contribute to cell degeneration and promote the development of pancreatic cancer. Researchers led by Dr. Ivonne Regel were able to show for the first time that the signaling pathway plays an important role in inflammatory responses not only in immune cells, but is also active in pancreatic cells of precursor lesions and tumor cells. This activation of the signaling pathway has an important function in pancreatic cancer development. Genetically-altered mice lacking a functional signaling pathway are unable to develop pancreatic carcinomas (see Figure). Similarly, it was genetically knocked out in pancreatic tumor cells using CRISPR/Cas9 gene scissors. These genetically modified tumor cells exhibited significantly less aggressive behavior in cell culture experiments and also showed greatly reduced metastasis in animal models.
“For the first time, we were able to demonstrate that an active signaling pathway in pancreatic cells contributes to the development of pancreatic cancer and also supports the formation of metastases.”

Dr. Regel’s team has made another exciting discovery: In pancreatic tumor cells, the signaling pathway surprisingly does not regulate known target genes; instead, evidence was found for epigenetic modifications. These are regulatory modifications to DNA and packaging proteins (histones) that influence the activity of genes. Thus, the current research results indicate that activation of the signaling pathway in tumor cells leads to high levels of transcription of specific tumor-promoting genes.
These genes primarily regulate tumor cell metabolism. This is particularly important because metabolites of tumor cells can be found in the blood of patients and can be used as biomarkers. “My team and I have succeeded in identifying different subtypes of pancreatic cancer from the blood of cancer patients based on differences in their metabolic programs” said Dr. Regel. “In further studies, we now want to find out to what extent the development of pancreatic cancer subtypes is regulated by the signaling pathway.”
